Treating hearing loss may slow memory decline in people with more risk factors
What the study found
ACHIEVE is a U.S. study involving 977 older adults with hearing loss. Half received hearing aids and regular care from hearing specialists. The other half attended classes about healthy aging. Overall, hearing treatment did not slow memory and thinking decline for everyone. In a new analysis published in 2025, researchers divided participants according to their risk of mental decline. They used information such as age, blood pressure, diabetes, and education. Among the participants at highest risk, the quarter with the most risk factors, the decline in memory and thinking skills over three years was about 62% slower in those who received hearing treatment.
What this means in practice
Hearing loss is more than an inconvenience. It can make conversations, going out, and staying mentally active more difficult. If you often ask people to repeat themselves or need to turn the television volume up very high, consider having your hearing tested. Hearing aids work best when they are properly adjusted and regularly checked by a professional. Simply buying one and leaving it in a drawer will not help.
Study limitations
This was a secondary analysis carried out after the main study, which did not find a benefit for everyone. The results need to be confirmed by further research. Some of the study authors reported connections with hearing aid manufacturers.
